There are three videos that I've downloaded. I moved them to a different folder where I put all my videos, however a copy of the files still show up in my download directory. I tried (in Explorer and CMD) to delete them, move them, rename them, open them but Windows says "Could not find this item." so the file no longer exist in that directory but it still appears there. How can I remove these from my download folder? I have also tried to replace the file with another by saving over it but instead they sit next to each other side by side and I can delete either one but after that, the other can't be deleted. They also take up no space.
I am using Windows 7 and the files were downloaded via Firefox onto an NTFS file system.
